How can you tell when plum jam is done?

[Kenz]

Hi there! I'm new to making plum jam and I'm not sure how to tell when it's done cooking. Are there specific signs to look for, or any tests you use to check if it's ready? Any tips would be super helpful. Thanks a bunch!

Hi there! Making plum jam is such a fun project! You can tell it's done cooking when it thickens and starts to coat the back of a spoon; if you run your finger through it, it should leave a clear line. Another good test is the “plate test” where you put a small spoonful of jam on a cold plate, let it sit for a minute, and then push it with your finger. If it wrinkles and holds its shape, it’s ready! Enjoy your jam-making adventure!

Hey there! Making plum jam is super fun! To tell when it’s done, look for these signs:

1. Bubble Test: The bubbles will get bigger and slower as it thickens.
2. Temperature: If you have a candy thermometer, aim for about 220°F (104°C).
3. Plate Test: Put a spoonful on a chilled plate and let it sit for a minute. Run your finger through it; if it holds its shape, it’s ready!

Happy jam-making!
